I know some diabetics who had to go on injections but later on were able to stop all diabetes medication. The reason they couldn't control bg at first was the dietary advice to have carbs. When they did the opposite they didn't need neither insulin nor metformin. Another friend of mine is on insulin and morbidly obese. He still clings to the dieticians advice and eats a lot of bread. It makes me so sad as I know I will loose him, he already had two heart attacks. We have been friends since our teens. I think the advice he gets is criminal. It will kill him.
